This paper concerns a novel method of constructing shell structures from flat concrete plates by means of active bending. The method is described together with a series of experimental investigations. The theoretical background for this method is given in Berger et al., Actively bent concrete shells, Struct Concrete, 2020. The method makes use of the high capacity for rotation exhibited by thin concrete plates that are reinforced with highly elastic tensile reinforcement. When these plates are subjected to eccentrical forces introduced by external tendons they are raised and bent precisely into a desired curved shape. The method was investigated and refined along with a series of experiments which are the subject of this paper: uniaxial tensile tests on rovings to determine their elongation at fracture, bending tests on small concrete plates to determine possible radii of curvature, and large‐scale tests to demonstrate the erection process of actively bent shells.

主动弯曲混凝土壳体的试验研究

本文涉及一种通过主动弯曲从扁平混凝土板构造壳体结构的新方法。该方法与一系列实验研究一起进行了描述。该方法的理论背景在Berger等人的《主动弯曲的混凝土壳体》，《结构混凝土》，2020年中给出。该方法利用了薄的混凝土板表现出的高旋转能力，而薄的混凝土板则通过高弹性抗拉增强件进行了加固。当这些板承受由外部筋引入的偏心力时，它们会被升高并精确地弯曲成所需的弯曲形状。对该方法进行了研究和完善，并进行了一系列的实验，这些实验是本文的主题：粗纱的单轴拉伸试验，以确定其断裂伸长率，
